Hello all,
I am working on a command that concats two videos from my camera, and then
overlays another video on top of the concatonated video. It is mostly
working, but the timing isn't right. For sake of argument, let's say that
MVI_0001.MOV is 5 min, and MVI_0002.MOV is 3 min (they are broken up by my
camera, but I just want them together), and overlay.avi is ~8 minutes. I
want to delay the overlay video 1.1 seconds to align the videos. But when
I run this command, unless I'm missing something, the first 5 minutes are
fine, but then the alignment of the overlay is off for the last three
minutes (it's like it isn't delayed for the last 3 minutes). Does anyone
see what is wrong with my command?
ffmpeg -i MVI_0001.MOV -i MVI_0002.MOV -ss 1.1 -i overlay.avi -filter_complex
"[0:0][0:1][1:0][1:1]concat=n=2:v=1:a=1 [v][a];
[v][2:0]overlay=format=rgb[vout]" -strict -2 -shortest -map [vout] -map [a] out.mp4
